When I apply your patch to the latest SVN (r50920), I don't get the same error,
I get what amounts to an "unregistered hf" (perhaps corruptted?) in the first
proto_tree_add_item call in the giant while loop in dissect_rsvp_msg_tree(). 
It's seems a byproduct of the hf_rsvp_filter array architecture (which I really
don't like, by the way).  Maybe you're putting the XRO object enumeration at
the wrong offset?
